help with the slip clutch

[schatts]

i have a e maxx with the 2000kv tekin motor running on 22.2v system. and i cant get the friction pads to stick. i have even upgraded to the hd pads. i have sanded back the pads and i just burn them out right away. what do i do to make this rock solid and not burn out after five mins of driving

[bentrocker]

Are you locking the slipper down when you tighten the slipper ? On the other side of the tranny where the shaft protrudes that the slipper is attached to. There is a hole in the shaft. Put something in there to keep the shaft from turning. Tighten the slipper nut until it is tight then back it of a touch. Try that first.

did you break in the new pads?? don't use 2/3s, for break in, or if you do take it real easy on the throttle.gl2u.....

• Slipper Clutch Break-In
The E-Maxx Brushless Edition’s slipper clutch requires a break-in procedure
to ensure consistent operation with the extremely high power output of
the included Castle Creations Mamba Monster brushless motor system. The
slipper clutch has been adjusted to the correct initial setting for break-in.
Follow these steps to ensure maximum performance and life from your
slipper clutch:
1. Make your first runs with the model using the stock gearing and 6- or
7-cell NiMH packs, or 2S LiPo packs.
2. Drive normally. The slipper clutch should slip momentarily when
accelerating aggressively on high-traction surfaces (you will hear a
whirring sound when the slipper clutch allows the spur gear to slip).
3. If excessive slippage is noticed (slipping that lasts for more than 3
seconds under hard acceleration), or the slipper clutch slips anytime
the throttle is applied at any lever, stop driving immediately. Let the
slipper clutch cool for 10-15 minutes. When the clutch is cool, test-drive
the vehicle again. If you still experience excessive slippage, allow the
slipper to cool once more, then tighten the slipper nut ¼ turn (turn the
nut clockwise) and repeat the break-in process. Do not adjust the slipper
clutch before it has cooled.
4. Continue to run the vehicle and monitor slipper clutch performance as
noted above, and readjust if necessary. When the run is complete, the
slipper should be fully broken in.
After break-in, the slipper clutch is ready for any type of driving, with any
batteries up to 6S Lipo. Set the slipper clutch so it only slips for a moment
(if at all) under hard acceleration in high-traction conditions. If excessive
slippage is noticed, stop driving immediately. Continuing to drive with a
loose slipper will cause damage to the slipper unit. You must let the slipper
cool down to ambient temperature before tightening the slipper nut and
resuming driving.

Yup, what he said ^^^ haha.

How did you make out ? Is your slipper working now?

[schatts]

OK i didn't break in the pad the way i should of. so i threw a new set in and broke them in with a pair of nimh. after i went back to the 6s it acts the same way. i made it about 2 mins. then the back side of the slip disk melted the pot aluminum all the way to the motor plate past the little pin. what the... the truck spins freely. and yes i know about the hole in the back of the shaft. i ordered some new parts on eBay today to replace the hole slip assembly. this will be the 4th time replacing this after i put the tekin motor in.

does anyone out there have a powerful system and had this problem and fixed it. if so how

[bentrocker]

I am running a 1800kv castle motor and I have no issues with the slipper on 6s. It will do double back flips from a dead stop on pavement. I am still on my original hd slipper for 1 year.
Have you locked down the slipper?

[schatts]

what do you mean by lock down. the spring is all the way tight. yes

[bentrocker]

That is what I meant by locked down. I tight'n mine down till I can't turn the nut any more and come back maybe 1/16".

Maybe try it pretty loose. I had the same problem it was too tight. I ran mine as tight as it would go then 1/4-1/2 loosened

[schatts]

ok those look like the answer. did you try any of them and did they work

[schatts]

ya i try as tight as humanly possible, i tryed a 1/4 to 1/2 turn back. has anyone tryed the mods 87gn posted.

[schatts]

what i'm going to dis. get a new slip gear assembly again. the whole thing. and try to properly break them in. if that doesn't work than i'm going to put a pop rivet in it.

Make sure you post some pics of that. lol There was a couple guys on here a few weeks ago that tried that mod. I think mayhem6969 did it to his maxx before he sold it.

[bentrocker]

So have you hauled out the pop rivet gun yet ?

[schatts]

not yet, i had to replace the chassis, steering linkage, and front skid plate, that i dont have. i did put another slip assembly in. all complete new to the tranie. im going to give a whirl one more time. i just talk to a old friend finding out he's kinda a guru when it come to rc. im going to let him look at it and im going to run it for him to see what he thinks

[bentrocker]

So what did your guru find ? Did you get your slipper to stop slipping? In a sick way I would like to see what a rivited slipper would look like. lol!

[schatts]

ya i got it to stop slipping. i replace the whole assmbily from the tran. forward. i guess there are some carbon fiber pads that came out that will hold up to 8s. im look ing to a par of those. and i might just trying riving one down just to see it works
